Patent CA-2275617-C (CA)
Inventor: DA PONTE MANUEL DOS SANTOS
IPC: H02P/
Filed: 1997-12-19
Granted: 2007-05-29
Abstract: A hybrid generator set comprises an engine/generator or another controllable electrical source (10) which provides a variable voltage electrical output, this output is rectified and fed to a DC to DC converter (12), the output (VDC) of which is monitored by a control circuit (16). This output serves as an intermediate DC output, which typically is us ed to power an inverter (14) to generate an AC output which supplies an external load. The use of the DC to DC converter isolates the intermediate DC output from the generator output, and allows the generator set to operate efficiently over a wide engine/generator speed range, according to load demand.

Abstract: When an IP (Information Provider) server is accessed from a mobile station, a gateway server determines whether or not the IP server is to be IP billed (S101). If it is not to be IP billed, then user billing is applied. In this case, the gateway server sends a user management number of the mobile station and the number of exchanged packets to a billing system (S102). The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the user specified by the user management number (S103). On the other hand, if the accessed IP server is to be IP  billed, then IP billing is applied. In this case, the gateway server sends the number of exchanged packets and the address of the accessed IP server to the billing system (S104). The billing system calculates a communication fee in accordance with the number of packets, and issues a bill to the IP (S105).

Granted: 2005-09-13
Abstract: A fenestration product such as a door or a window includes a plurality of frame members positioned in a surrounding relationship about a panel, each of the members having a pair of opposite open ends. A plurality of corner locks couple the beveled ends of the frame members together to form secure corners of the frame. A miter joint interface line is defined between the abutting, beveled ends of the members at each corner. Each comer lock comprises a generally L-shaped body having a pair of legs that are secured within the open ends of the corresponding frame members.  A pair of parallel sealant channels extend along the back, top and front of the body and are disposed on opposite sides of and laterally offset from the interface line so that sealant filling the channels creates a pair of parallel seal paths between the lock and the frame that are laterally offset from the interface line. This keeps the sealant from escaping through the interface line onto the decorative surface of the frame and creating an unsightly deposit, yet provides a secure seal against the environment. A small notch in the frame at each corner allows a small amount of the sealant to flow out of the corner and onto the non-decorative surface of the frame for covering the interface line on the non-decorative surface.

Abstract: Technique permettant de suturer un tissu biologique mou (2) présentant une incision (4) au moyen d'un forceps (8) conçu pour saisir une partie dudit tissu des deux côtés de l'incision. Des électrodes (11) fixées sur le forceps entrent en contact avec la partie de tissu. Une source d'alimentation électrique (11) applique aux électrodes un signal électrique haute fréquence destiné à traverser la partie de tissu. La source est commandée de façon à appliquer aux électrodes un signal de tension durant une première étape et un autre signal de tension durant une seconde étape. Durant la première étape, la tension monte d'une manière linéaire. Durant la seconde, elle est stabilisée et modulée par un signal rectangulaire basse fréquence. Un système de serrage applique, par l'intermédiaire du forceps, une force qui comprime le tissu avec un seul niveau d'intensité ou avec différents niveaux sur deux temps, pendant que la tension haute fréquence traverse les électrodes. L'impédance tissulaire est mesurée en fonction du temps, avec détermination de sa valeur minimale, puis mise en mémoire.

Title: Method and device for processing fresh meat
Inventor: SCHLEGEL JURGEN
IPC: A23B4/09
Filed: 1998-09-10
Granted: 2007-11-20
Abstract: The invention relates to a method for processing fresh meat and fish. The fresh meat is stored during a set time in an airtight chamber (1) to be locked after oxygen has been supplied thereto, in an atmosphere comprised mainly of oxygen, under a pressure higher than the atmospheric pressure. During the oxygen supply process (12), the temperature is selected at such a level and the supply set/controlled at so low a speed that the fresh meat cannot freeze. During storage, the pressure is so high and the storage duration so long that the fresh meat is entirely impregnated with oxygen. Furthermore, the oxygen exhaust is set/controlled at sufficiently low a speed to prevent fresh meat from freezing and enable the oxygen with which the processed fresh meat is impregnated to be removed with no blistering.
